Resources for product selection, quality review and custom chemistry planning
Use these practical guides and checklists to compare products, prepare custom requests and align documentation expectations before placing an inquiry.
Technical guides
Practical selection guides for catalog products and custom chemistry planning.
How to evaluate phosphoramidites
Compare base identity, protecting groups, 2′ modification, coupling performance, storage sensitivity and downstream deprotection compatibility before choosing a monomer.
Choosing modified nucleosides and nucleotides
Review salt form, hydration state, enzymatic compatibility, incorporation context, analytical method and storage before using modified inputs in RNA or assay workflows.
Selecting sulfurizing reagents and coupling activators
Match reagent identity, solubility, reaction rate, odor/safety profile, byproduct behavior and process scale to the desired oligonucleotide synthesis workflow.
GalNAc linker and conjugation planning
Compare ligand valency, linker length, attachment chemistry, steric profile and analytical traceability before requesting a custom conjugation intermediate.
Working with stereodefined phosphorothioate
Decide first whether the sequence needs defined Rp/Sp configuration at all, then choose the chiral auxiliary that delivers it — DPSE or PSM, D or L. Plan the diastereomeric reference standards before the campaign rather than after: without them the configuration cannot be demonstrated.
Quality & documentation
What to align before ordering or requesting custom material.
CoA and lot documentation
Confirm identity, purity, assay basis, appearance, storage recommendation and analytical method expectations before material release.
Purity and specification basis
Define whether purity is reported by HPLC/UPLC area, assay, NMR, LC-MS or another agreed method, especially for salts and hydrated materials.
Storage and handling notes
Sensitive nucleotides, amidites, dyes and reactive handles may require dry, low-temperature or light-protected handling.
Reference and impurity standards
Use defined standards to support method development, impurity tracking, forced-degradation work and release-method qualification.
Selection tools
Short checklists that make product selection and quote requests faster.
Search inputs
Use product name, CAS number, synonym, target structure, class name or application keyword in the site-wide search.
Chemistry fit
List the product family, intended reaction, solvent system, target sequence or biological assay where relevant.
Specification needs
State desired purity, counterion or salt form, water content concern, analytical method and documentation requirements.
Scale and packaging
Pack size is customized to customer requirements; provide near-term need and likely future demand.
Application notes
Use-case oriented notes for product selection and research planning.
mRNA and cap analog workflows
Materials may support in-vitro transcription, capping strategy evaluation, modified nucleotide screening and analytical method development.
Modified oligonucleotide synthesis
Phosphoramidites, sulfurizing reagents, activators and solid-support related materials can be selected around coupling, sulfurization and deprotection needs.
Fluorescent, biotin and click-enabled labeling
Functionalized materials support detection, capture, conjugation, immobilization and probe-development studies.
Non-GMP tox material planning
For early research or toxicology-enabling work, align scale, specification, impurity control and documentation before synthesis begins.
FAQ
Common questions before contacting BX Lab.
Can BX Lab recommend a product?
Yes. Share the target workflow, sequence context or structure, and our team can suggest a catalog product or custom route.
What if a CAS number is not available?
Send the structure, SMILES, drawing or reference profile. Some novel or custom materials may not have an assigned CAS number.
Can pack size be customized?
Yes. Pack size is customized to customer requirements based on feasibility, material stability and project scale.
Are materials GMP?
No. The catalog and custom materials described on this site are supplied for research use and are non-GMP.
Custom project request checklist
For the fastest technical review, include the following information in your first message.
| Target | Product name, CAS number, structure, SMILES, drawing or target material profile. |
|---|---|
| Use context | Catalog purchase, screening, custom synthesis, process development, reference standard, impurity standard or non-GMP tox material. |
| Quantity | Desired amount, acceptable staged delivery and expected future scale. |
| Specification | Target purity, salt form, counterion, water content concern, residual solvent limits and analytical method requirements. |
| Documentation | CoA, analytical summary, storage guidance, method notes or additional project-specific documents. |
| Timeline | Requested delivery window and any critical study, campaign or screening dates. |
