Certified Reference Materials for Quantitative and Qualitative Analysis

Analytical Standard Grade products from Aladdin Scientific are high-purity chemicals and solutions developed for use as primary or secondary reference standards in a wide range of analytical testing, method validation, and instrument calibration workflows. Each compound is supplied with full documentation supporting its use in traceable, reproducible, and regulated analytical applications.

Key Features

· High Chemical Purity (Typically ≥99.5%)
Precisely characterized and controlled to ensure lot-to-lot reproducibility.

· Accurate Composition and Traceability
Identity and concentration verified by NMR, HPLC, GC, MS, KF, or titration methods. Traceable to international or pharmacopeial reference materials (where applicable).

· Accompanied by Detailed Certificate of Analysis (CoA)
Includes molecular identity, purity, assay method, water content, residual solvents, and measurement uncertainty (for certified reference materials).

· Stability and Packaging
Packaged under inert atmosphere or sealed in ampoules to preserve stability and concentration over time. Suitable for long-term archival and use in regulated environments.

Typical Applications

· Calibration of analytical instruments (HPLC, GC, LC-MS, UV-Vis)

· Standard curve generation for quantitative assays

· Method validation and system suitability testing

· Regulatory and compendial testing (e.g., pharmacopeial, environmental, forensic)

· Control of process consistency in QA/QC laboratories

Available Formats

· Neat solids or liquids (≥99.5% purity)

· Pre-weighed ampoules or solution standards (e.g., 1000 µg/mL in MeOH or ACN)

· Custom concentrations, blends, and multi-component standards available on request

Why Choose Aladdin Analytical Standards?

· Manufactured in ISO-compliant and traceable labs

· Backed by complete characterization and validated methodology

· Ideal for use in GLP, GMP, ISO/IEC 17025, and regulatory compliance testing

· Supplied with CoA and optional SDS, IR/NMR/MS spectra

Standard Grade Comparison Analytical vs CRM vs USP vs Working

Attribute	Analytical Standard Grade	Certified Reference Material (CRM)	USP/EP Standard	Working Standard
Typical Purity	≥99.5%	≥99.9% or certified value	Defined by pharmacopeial monograph	Varies (often ≥98%)
Traceability	Traceable to reference compound (internal or external)	Traceable to SI or national metrology institute	Traceable to pharmacopeial authority	Calibrated against certified or pharmacopeial standard
Certificate of Analysis (CoA)	Detailed CoA with purity, method, lot info	Extensive CoA with uncertainty, homogeneity, stability data	Monograph-aligned CoA or ID sheet	Internal CoA or assay report
Measurement Uncertainty	Not always specified	Yes (quantified)	Not quantified (implicit)	Not typically specified
Regulatory Acceptance	Accepted in general analytical labs	Globally accepted for ISO/IEC 17025, GMP, GLP	Required for pharmacopoeial compliance (e.g., FDA, EMA)	Internal lab use only
Usage Type	Quantitative/qualitative analysis	Primary standard for method validation	Reference standard for compendial tests	Secondary/backup standard
Primary Applications	Instrument calibration, method validation	Validation, accreditation, regulated testing	Drug substance/product testing, release assays	Routine QC tests, in-house calibration
Packaging	Solid, liquid, or ampoule; sealed packaging	Sealed ampoule, freeze-dried, or matrix-based	Controlled formats (neat or ampoule)	Flexible formats (bulk or small vials)
