Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 195.69 g/mol gives L-Isoleucine Ethyl Ester Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
L-Isoleucine Ethyl Ester Hydrochloride (CAS 56782-52-6), molecular formula C8H17NO2HCl and molecular weight 195.69 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, L-Isoleucine Ethyl Ester Hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 195.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
