UNII R16CO5Y76E

Unique Ingredient Identifier: R16CO5Y76E

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: C9H8O4

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

Preferred Substance Name: ASPIRIN

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.

InChIKey: BSYNRYMUTXBXSQ-UHFFFAOYSA-N

The InChIKey to a unique identifier for a specific substance or ingredient that is based on its molecular structure. InChIKey stands for International Chemical Identifier Key and is a fixed-length string created from the IUPAC International Chemical Identifier (InChI). The InChIKey is useful in drug development and chemical analysis, where the molecular structure of a substance is an important factor in determining its properties and effects.

SMILES: c1(C(=O)O)c(OC(=O)C)cccc1

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: 50-78-2

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: C287

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: 1191 (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: 2244

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.

Ingredient Type: INGREDIENT SUBSTANCE

Substance Type: a05ec20c-8fe2-4e02-ba7f-df69e5e30248

The International Organization for Standardization - ISO 11238 substance type is used as a data element in the UNII code system to provide additional information about the type of substance being identified.
