UNII MRK240IY2L

Unique Ingredient Identifier: MRK240IY2L

The Unique Ingredient Identifier (UNII) is a unique alphanumeric code assigned to a specific substance or ingredient by the FDA (Food and Drug Administration). UNII codes are non-proprietary, free, unique, unambiguous and nonsemantic. Each UNII code consists of 10 characters with both letters and numbers. The first two characters represent the source of the substance while the remaining eight characters represent the specific substance. UNII codes are primarily used to identify and track substances in several drug databases and regulatory documents related to drugs, biologics, and medical devices.

Formula: 1291

Molecular Formula, total atoms represented as a molecular structure in a UNII description.

Preferred Substance Name: AZATHIOPRINE

The Preferred Substance Name (PSN) is the official or preferred name of a substance or ingredient. The preferred name provides a standardized and consistent name for each substance is used in the UNII code system. The preferred name may differ from other names also commonly used to refer the same substance. The PSN is usually the name used by regulatory agencies like the FDA.

SMILES: C9H7N7O2S

The Simplified Molecular Input Line Entry System or SMILES is a format used to represent and describe the molecular structure of a substance or ingredient. SMILES uses a series of alphanumeric characters to represent the atoms and bonds in a molecule in conjunction with other symbols and operators to indicate the arrangement and connectivity of the atoms.

Registry Number: 446-86-6

The Registry Number is the unique numerical identifiers assigned to a substance or ingredient by the Chemical Abstracts Service (CAS). The CAS registry number is a used and recognized standard identifier by many industries and regulatory agencies. The Registry Number facilitates cross-referencing substances between different databases that may use different naming conventions or identifiers.

NCI Thesaurus Concept Code: C290

The NCI Thesaurus give reference terminology for many systems. The code includes vocabulary for clinical care, translational research, basic research, public information and administrative activities.

UNII to RxNorm Crosswalk: 1256 (RXCUI)

The RxNorm Ingredient Concept Code is the numeric code assigned to a specific substance or ingredient by the National Library of Medicine's RxNorm system. By including the RxNorm code in the UNII code system it is possible to crossover UNII codes to RxNom.

PubChem Compound ID: 2265

The PubChem Compound ID is a unique identifier for a specific substance or ingredient in the PubChem database which is the largest collection of freely accessible chemical information by the National Center for Biotechnology Information. The PubChem database is a resource for drug discovery, development, chemical research, and other applications.

ITIS TSN: DTXSID4020119

The Taxonomic Serial Number is a unique identifier for a specific species of organism in the Integrated Taxonomic Information System. The ITIS is a comprehensive database of taxonomic information on plants, animals, fungi, and microbes, maintained by a partnership of several US government agencies.
