Chemical Structure

(R)-Carbidopa CAS 28875-92-5 chemical structure

Description

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.

(R)-Carbidopa (CAS 28875-92-5) is a high-purity analytical reference standard with the molecular formula C10H14N2O4 and a molecular weight of 226.23 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (R)-Carbidopa is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 226.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
