Chemical Structure

tert-Butyl 3-Fluoro-4-((hydroxyimino)methyl)-4-ethylpiperidine-1-carboxylate CAS 1400765-53-8 chemical structure

Description

The occurrence of tert-Butyl 3-Fluoro-4-((hydroxyimino)methyl)-4-ethylpiperidine-1-carboxylate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

tert-Butyl 3-Fluoro-4-((hydroxyimino)methyl)-4-ethylpiperidine-1-carboxylate (CAS 1400765-53-8), molecular formula C12H21FN2O3 and molecular weight 260.31 g/mol, is a CATO reference standard with documented purity and traceability.

tert-Butyl 3-Fluoro-4-((hydroxyimino)methyl)-4-ethylpiperidine-1-carboxylate (C12H21FN2O3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), tert-Butyl 3-Fluoro-4-((hydroxyimino)methyl)-4-ethylpiperidine-1-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
