Chemical Structure

Heparin calcium for NMR identification CRS CAS 37270-89-6 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO supplies Heparin calcium for NMR identification CRS (CAS 37270-89-6), a certified reference material (molecular formula N/A, MW N/A g/mol) for analytical method development and quality control.

Heparin calcium for NMR identification CRS is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
