Chemical Structure

(±)-2-Methylbutyryl-d9 Chloride CAS 1219795-10-4 chemical structure

Description

(±)-2-Methylbutyryl-d9 Chloride (CAS 1219795-10-4) is a high-purity analytical reference standard with the molecular formula C5D9ClO and a molecular weight of 129.63 g/mol.

The molecular framework of (±)-2-Methylbutyryl-d9 Chloride (C5D9ClO) is characterized by deuterium isotope labeling, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
