Your Challenge. Our Answer.

We understand the specific problems you face — and we built solutions for each one.

The Problem

Guanidinylation side products cap peptide chains and reduce crude purity with uronium reagents (HATU, HBTU)

Mironova’s Answer

DMTMM activates via a triazine mechanism — structurally incapable of guanidinylation, eliminating this entire impurity class

The Problem

HOBt-based coupling systems (PyBOP) are classified as explosives for transport, complicating procurement and plant siting

Mironova’s Answer

DMTMM thermal onset is 163 °C with −1 956 J/g — classified "Use with Caution," not shock-sensitive. No HOBt required.

The Problem

Catalog-grade reagents at 95% purity increase impurity burden and purification cycles at multi-kg scale

Mironova’s Answer

Mironova supplies all DMTMM salts at ≥99.0% (HPLC) from our US facility — 80% less impurity mass vs 95% material

The Problem

Lipidation steps for GLP-1 peptides (semaglutide, tirzepatide class) are quality-critical and sensitive to coupling-reagent choice

Mironova’s Answer

DMTMM mechanistically avoids guanidinylation in fatty diacid attachment. No published manufacturing data yet — evaluation kits available.

Published Evidence

Key findings from peer-reviewed literature relevant to your application.

BF₄ "Superactive Ester" in SPPS

80–100% coupling yields with high enantiomeric purity. Faster fragment synthesis than TBTU or HATU; purer crude than TBTU or PyBOP in automated SPPS.

Kamiński et al., J. Am. Chem. Soc. 2005

Thermal Safety Profile

DSC screening of 45 coupling reagents: DMTMM onset 163 °C, −1 956 J/g, not shock-sensitive. HATU/HBTU classified "Least Preferred." HOBt dry: propagates detonation.

Sperry et al., Org. Process Res. Dev. 2018

No Guanidinylation Mechanism

Uronium/guanidinium reagents produce guanidino side products that cap peptide chains. DMTMM lacks the uronium moiety entirely.

Vrettos et al., RSC Advances 2017

DMTMM in GLP-1 Class Peptide Assembly

DMTMM used in liquid-phase C-terminal assembly of tirzepatide, demonstrating utility for GLP-1 class peptide fragment coupling.

Agrawal et al., Org. Process Res. Dev. 2025

Peptide Reagent Market Growth

Peptide synthesis reagents market estimated at ~$730M (2024) growing to ~$1.5B by 2034, driven by GLP-1 and peptide therapeutic pipelines.

Mironova Strategic Analysis

SPPS & Lipidation Conditions

  • Solvent: NMP or DMF/NMP mixtures (BF₄ has limited solubility in pure DMF)
  • Equivalents: 1.5–3.0 eq relative to amino acid
  • Temperature: 20–25 °C (room temperature)
  • Time: 30–60 min per coupling cycle
  • Base: NMM or collidine — avoid DIPEA to minimize epimerization
