A linear tripeptide, H-Ala-Glu-Asp-OH (single-letter AED; also coded T-31), of L-alanine, L-glutamic acid and L-aspartic acid with free termini. Formula C12H19N3O8 from the three residues less two waters. Identity is reconciled against PubChem CID 87815447: the stereo-defined InChIKey KXEVYGKATAMXJJ-ACZMJKKPSA-N derived from the sequence matches the deposited record exactly (molecular formula and full InChIKey), with no unassigned stereocentres. The CAS number 85806-95-7 is checksum-valid but single-source and is flagged for confirmation. A computed 3D conformer is held pending the chemist sign-off.

Reference context

Cartalax is a synthetic tripeptide, H-Ala-Glu-Asp-OH (single-letter AED), of L-alanine, L-glutamic acid and L-aspartic acid, also coded T-31, from the St. Petersburg (Khavinson) line of short peptide bioregulators. It is listed here strictly as an analytical reference entity — it is not sold, stocked, or certified by Lineará, and has no price or certificate of analysis. The data on this page is characterization only: molecular formula C12H19N3O8 and the values computed from it. No biological activity, mechanism, or use is described or implied.

How Cartalax is characterized

Identity rests on the molecular formula and mass. Electrospray mass spectrometry (ESI-MS) measures the mass-to-charge ratio of the intact molecule; the average and monoisotopic masses are computed from the verified formula and cross-check the composition. The residue sequence and the modifications noted above define the structure.

It is listed here strictly as an analytical reference entity — it is not sold, stocked, or certified by Lineará, and has no price or certificate of analysis. The data on this page is characterization only: molecular formula C12H19N3O8 and the values computed from it. No biological activity, mechanism, or use is described or implied.
What is the amino-acid sequence of Cartalax?
Cartalax has the sequence Ala-Glu-Asp. A linear tripeptide, H-Ala-Glu-Asp-OH (single-letter AED; also coded T-31), of L-alanine, L-glutamic acid and L-aspartic acid with free termini. Formula C12H19N3O8 from the three residues less two waters. Identity is reconciled against PubChem CID 87815447: the stereo-defined InChIKey KXEVYGKATAMXJJ-ACZMJKKPSA-N derived from the sequence matches the deposited record exactly (molecular formula and full InChIKey), with no unassigned stereocentres. The CAS number 85806-95-7 is checksum-valid but single-source and is flagged for confirmation. A computed 3D conformer is held pending the chemist sign-off.
What is the molecular formula of Cartalax?
Cartalax has the molecular formula C12H19N3O8, giving an average molecular weight of 333.30 g/mol and a computed monoisotopic mass of 333.1172 Da.
What are the key chemical identifiers for Cartalax?
The CAS Registry Number for Cartalax is 85806-95-7. Its PubChem CID is 87815447 and its InChIKey is KXEVYGKATAMXJJ-ACZMJKKPSA-N.
Is Cartalax a peptide?
Yes. Cartalax is a peptide — a chain of amino-acid residues joined by peptide bonds, 3 residues in length. Its identity is defined by that sequence and its molecular mass.
How is Cartalax stored and reconstituted?
As a research material, Cartalax is typically handled as a lyophilized (freeze-dried) powder. It is kept desiccated and cold — commonly 2–8 °C for short periods and −20 °C for longer storage — and reconstituted in sterile or bacteriostatic water. This is storage and handling information only, not a use protocol.
Does Lineará sell Cartalax?
No. Cartalax is listed here only as an analytical reference entity. It is not part of the Lineará formulary, has no price or certificate of analysis, and is not offered for sale.
Is Cartalax approved for human use?
No. Cartalax is presented strictly as characterization reference data. It is not a drug, is not approved for any human or veterinary use, and must not be administered to humans or animals.
