Solubility: soluble in H 2 O, MeOH, slightly soluble in CH 3 CN, and DMSO. Suspended in CH 2 Cl 2, CHCl 3, THF, hexane, Et 2 O, and AcOEt. Form Supplied in: white solid; commercially available. Analysis of Reagent Purity: generally used as received. The efficiency of a series of well-known coupling reagents (TBTU, HATU, and PyBOP) and of newin situ activating reagents (TCTU, HCTU, and DMTMM) was compared by synthesizing the 65–74 fragment of the Acyl Carrier Protein (H-Val-Gln-Ala-Ala-Ile-Asp-Tyr-Ile-Asn-Gly-NH2), containing ‘a difficult sequence’, as a test peptide, in a multiple peptide synthesizer.
Both ways provide the same the desired glucuronic acid amide, but DMTMM as coupling reagent requires less the Schotten-Baumann procedure,the Weinreb amidation of esters and the classical coupling reaction using EDC,HBTU or DMTMM as the coupling agents. 1 Jul 2014 We tested the more reactive coupling reagent, DMTMM (23), for coupling hydrazides to carboxylic acids in proteins and protein complexes (Fig. a peptide-coupling reagent has particularly attracted organic chemists in DMTMM. 4-(4,6-dimethoxy[1,3,5]triazin-2-yl)-4- methylmorpholinium chloride.

The cycle of Fmoc deprotection and coupling was repeated adding to the growing pep-tides the following amino acids: Fmoc-Phe-OH (0.16 g, 0.4 mmol), Of the 45 peptide coupling reagents: • 7 had at least 1 experiment that flagged as potentially shock sensitive NDSC, PyBOP, TDBTU, TBTU, TCTU, HATU, HDMA • 12 had at least 1 experiment that flagged as potentially explosive NDSC, PyBOP, TDBTU, TBTU, TCTU, HATU, HDMA, PyAOP, DMTMM, TNTU, TPTU, HBTU Case Study: Peptide Coupling Reagents Entry 2002-03-01 The amidation proceeded successfully via DMTMM coupling, PFP-activation and TBD catalysis, although only the latter 2 methods selectively yielded the desired product.

CAS-nr: 3945-69-5; dmtmm 4 - 4,6-dimetoxytriazin-2-yl
Physical Data: mp 116–117 °C. Solubility: soluble in H 2 O, MeOH, slightly soluble in CH 3 CN, and DMSO.
• Very small bending moment. • Single diaphragm flexible coupling. • Allows angular misalignment up to 1/3°. Permanent magnetic couplings offer a reliable alternative to conventional dynamic seals due to their leakage-free transmission in pumps and agitators.

DMTMM-based coupling reactions were run in 200 mM MOPS buffer pH 7.0 (200 mM (3[N-morpholino]propanesulfonic acid, 20 mM sodium acetate, 10 mM EDTA) while EDC-based reactions were run in water. 2.4. General Procedure for Coupling Reactions. All reactions were run in a constant volume in the solvent preferred by the coupling reagent. DMTMM has been applied as a coupling reagent for the preparation of glycopolymers [49, 51] as well as for modification of carboxyl group-containing polysaccharides [62] and poly(L-glutamic acid 2014-08-08 Search results for DMTMM at Sigma-Aldrich.
