Structurally, 16255-48-4 DL2A9M9D6X Chloramphenicol stearate (R-(R*,R*))-2-((Dichloroacetyl)amino)-3-hydroxy-3-(4-nitrophenyl)propyl stearate Octadecanoic acid, 2-((dichloroacetyl)amino)-3-hydroxy-3-(4-nitrophenyl)propyl ester, (R-(R*,R*))- Stearic acid, alpha-ester with D-threo-(-)-2,2-dichloro-N-(beta-hydroxy-alpha-(hydroxymethyl)-p-nitrophenethyl)acetamide Octadecanoic acid, (2R,3R)-2-((dichloroacetyl)amino)-3-hydrdoxy-3-(4-nitrophenyl)propyl ester 4-13-00-02754 (Beilstein Handbook Reference) BRN 2797487 Chloramphenicol monostearate Chloroamphenicol stearate Chloroamphenicol stearic acid ester 2,2-Dichloro-N-(beta-hydroxy-alpha-(hydroxymethyl)-p-nitrophenethyl)acetamide alpha-stearate EINECS 240-363-4 Eusynthomycin Levomycetin stearate Madomicetina Stearic acid, ester with chloramphenicol UNII-DL2A9M9D6X (C29H46Cl2N2O6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 589.59 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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), 16255-48-4 DL2A9M9D6X Chloramphenicol stearate (R-(R*,R*))-2-((Dichloroacetyl)amino)-3-hydroxy-3-(4-nitrophenyl)propyl stearate Octadecanoic acid, 2-((dichloroacetyl)amino)-3-hydroxy-3-(4-nitrophenyl)propyl ester, (R-(R*,R*))- Stearic acid, alpha-ester with D-threo-(-)-2,2-dichloro-N-(beta-hydroxy-alpha-(hydroxymethyl)-p-nitrophenethyl)acetamide Octadecanoic acid, (2R,3R)-2-((dichloroacetyl)amino)-3-hydrdoxy-3-(4-nitrophenyl)propyl ester 4-13-00-02754 (Beilstein Handbook Reference) BRN 2797487 Chloramphenicol monostearate Chloroamphenicol stearate Chloroamphenicol stearic acid ester 2,2-Dichloro-N-(beta-hydroxy-alpha-(hydroxymethyl)-p-nitrophenethyl)acetamide alpha-stearate EINECS 240-363-4 Eusynthomycin Levomycetin stearate Madomicetina Stearic acid, ester with chloramphenicol UNII-DL2A9M9D6X meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
